如何将文件移动到 zip 存档的根目录中？

Question

所以我终于弄清楚了我的 GenEpub.py 程序的主要问题，以及为什么它会产生如 zip -t 和 zipinfo 所证明的压缩的、有效的 zip 文件，但它未能通过 epubcheck 的最终测试。

问题如下，下面的脚本写入了本例中称为IdealogicalEcho的整个文件夹，然后按照说明将其压缩并将压缩文件本身命名为IdealogicalEcho.epub。 epubcheck 但是看不到这个文件夹，然后报告三个核心 ePub 文件都找不到 mimetype META-INF OEBPS。

有没有办法将这些文件移动到 zip 目录的根目录？压缩前还是压缩后？

这是EpubGen.py的当前版本：

#!/usr/bin/env python

#GenEpub.py - Generates an .epub file from the data provided.
#Ideally with no errors or warnings from epubcheck (needs to be implemented, maybe with the Python wrapper).

import os
import json
import zipfile

with open('metadata.json') as json_file:
   data = json.load(json_file)

#The ePub standard requires deflated compression and a compression order.
zf = zipfile.ZipFile(data["fileName"] + '.epub', mode='w', compression=zipfile.ZIP_STORED)

zf.write(data["fileName"] + '/mimetype')

for dirname, subdirs, files in os.walk(data["fileName"] + '/META-INF'):
    zf.write(dirname)
    for filename in files:
        zf.write(os.path.join(dirname, filename))

for dirname, subdirs, files in os.walk(data["fileName"] + '/OEBPS'):
    zf.write(dirname)
    for filename in files:
        zf.write(os.path.join(dirname, filename))

zf.close()

#zipfile has a built-in validator for debugging
with open(data["fileName"] + '.epub','r') as f:
    if zipfile.is_zipfile(f) is True:
    print("ZIP file is valid.")

#Extra debugging information
#print(getinfo.compress_type(zf))
#print(getinfo.compress_size(zf))
#print(getinfo.file_size(zf))

还有metadata.json：

Answer 1

>>> z = ZipFile('test', 'w')
>>> help(z.write)
Help on method write in module zipfile:

write(self, filename, arcname=None, compress_type=None) method of zipfile.ZipFile instance
    Put the bytes from filename into the archive under the name
    arcname.

.write 的第二个参数用于 zip 文件，它指示在 zip 中存储文件的位置的名称。因此，对于您的示例，zf.write(data["fileName"] + '/mimetype', 'mimetype') 应该可以解决问题。
